The object of the present study is to introduce a means of comparing the Vostok and marine chronologies. Our strategy has been to use the δ18O of atmospheric O2 (denoted δ18Oatm) from the Vostok ice core as a proxy for the ...

Accumulation rates of microfossil associations are independent of each other and, in addition to percentages, give indispensable information about the significance of micropaleontological data. Marine diatoms reveal that ...

New oxygen isotope data and a high‐resolution carbonate record of a core from the northwest African margin are presented, in combination with geochemical (Zr/Rb ratio, Al, Ba, organic carbon, and biogenic opal fluxes) and ...

In the northwest Arabian Sea upwelling occurs each summer, driven by the strong SW monsoon winds. Upwelling results in high biological productivity and a distinctive assemblage of plankton species in the surface waters off ...

Samples from the upper portion of a cyclic pelagic carbonate sediment sequence in Deep‐Sea Drilling Project (DSDP) hole 503B (4.0°N, 95.6°W) are the first group to be analyzed for paleoceanographic and paleoclimatic ...

At the northern exit of the Vema Channel, in the Southern Brazil Basin, deep currents linked with Antarctic Bottom Water flow (AABW, below 4200 m) have formed contouritic accumulations along the continental rise. Lithologic ...

The importance of the hydrological cycle as a controlling factor on the magnitude of the thermohaline circulation is illustrated in a simple one‐hemisphere coupled ocean‐atmosphere box model. The ocean model includes ...

Direct indications of circulation patterns in the deep sea (especially along continental rises and sediment drifts) can be obtained through the analysis of abyssal bedforms such as furrows and mud waves. Such direct evidence ...

A major change in Cenozoic deep‐sea benthic foraminifera occurred in the Atlantic, Indian, and Pacific oceans near the Paleocene/Eocene boundary. Benthic foraminiferal abundance changes began at about 61.5 Ma at Pacific ...

A sediment wave field in the western Gulf of Mexico is similar to many other fields that are located on continental rises and related to thermohaline contour currents, especially western boundary undercurrents. Such currents ...

The episodes of ice‐rafted detritus (IRD) accumulation identified in North Atlantic sediment cores indicate periods of abnormal iceberg production mainly of the Laurentide Ice Sheet. In this paper we develop further a ...

There are advocates of the use of glauconite as a chronometer for geologic time scale studies who insist that if the geohistory of the sample in question is known in detail, one can ascertain before hand that the sample ...

Under modern conditions, the reoxygenation of eastern Mediterranean deep water is the result of the formation of dense bottom water in the southern Adriatic Sea. Oxygen isotopic records of planktonic foraminfera used as a ...

In the aftermath of the Cretaceous/Tertiary (K/T) boundary event (∼65 m.y. ago), pelagic carbonate productivity was greatly reduced for several hundred thousand years. A decrease in carbonate productivity by a factor greater ...

Detailed planktonic foraminiferal biostratigraphy from eight measured sections of Cretaceous limestone near Laytonville, California, indicates a composite sequence that extends in age from late Albian to early Turonian. ...

A general circulation model of the Indian Ocean was run using monthly average wind and thermal forcing from an atmospheric model for conditions appropriate for today and 9000 years B.P. The present‐day forcing is poor ...

In the North Atlantic we define H‐0 as a Heinrich‐like event which occurred during the Younger Dryas chron. On the SE Baffin shelf prior to 11 ka, surface water productivity was reasonably high, as measured by the numbers ...

Although the pulsating nature and the abruptness of the last deglaciation are well documented in marine and land records, very few marine records have so far been able to capture the high‐frequency climatic changes recorded ...

Results are presented of a high‐resolution study of the planktonic foraminiferal faunas from two piston cores recovered from the Cariaco Basin in the southern Caribbean Sea. The Cariaco Basin is a small anoxic marine basin ...

Planktonic foraminiferal abundances, fluxes, test sizes, and coiling properties are influenced in various ways by the southwest monsoon winds and associated upwelling in the western Arabian Sea. To determine the short‐term ...
